The paper explores the question of the relationship between the practice of original philosophical inquiry and the study of the history of philosophy. It is written from my point of view as someone starting a research project in the history of philosophy that calls this issue into question, in order to review my starting positions. I argue: first, that any philosopher is sufficiently embedded in culture that her practice is necessarily historical; second, that original work is in fact in part a reconstruction by reinterpretation of the past and that therefore it bears some relation to historiographic techniques for the restoration of damaged objects and texts; and third that the special oddities of the relations of present and past do not fail to ensnare the philosopher, who must restore the past but freely break from it. I describe this relationship as proleptic. Finally, I argue that this is a moral imperative in writing philosophy, derived from the imperative to be honest.
